Patent DE-4104862-A1 (DE)
Title: Double station spinner - uses rotating sliver cans to twist the sliver before drawing
Inventor: STAHLECKER FRITZ
IPC: D01H1/00
Filed: 1991-02-16
Abstract: The spinning machine, with double spinning stations, has two sliver cans for each station with drawing units for the drawn sliver to be spun and wound as a double yarn on a common bobbin. While the slivers (2a, 2b) are taken from the cans (8a, 8b), the cans are rotated round their axes to impart a twist on the slivers (2a, 2b) drawn off. The slivers (2a, 2b) have a count of Nm 0.4-0.8 and, through the rotation of the sliver cans (8a, 8b), are twisted at the rate of 1-15 twists/m as they are drawn out of the cans. The cans (8a, 8b) are rotated by one or more drives. The double spinning stations (1) have three-cylinder drawing units (10a, 10b) for the slivers (2a, 2b) delivered to each section of the station. The support for each can (8a, 8b) has a drive mechanism to rotate at least one of the cans (8a, 8b), where the drive is recessed within the base of the can support. The can rotation can be interrupted at each can support. The can drive can be applied at the edge by at least one drive system. A common drive can be used for all the spinning stations, with the drive running along the line of the spinning assembly to rotate the cans. ADVANTAGE - The provision of twisted sliver reduces the loading on the spinning stations.

Title: Actively controlled press ram hydraulic cushioning system - has displacement transducers to detect ram misalignment and signal correcting oil input to lowest indicating cylinder
Inventor: WANZKE LOTHAR
IPC: B30B15/24
Filed: 1991-07-30
Abstract: The system is applicable to forming presses generally in which an upper tool secured to the ram works in conjunction with a lower tool secured to the press table. Between the ram and platform is interposed a hydraulic cushioning arrangement with at least two cylinders for correcting tipping movements and preserving parallelism of the tool locating surfaces of ram and platform. Around the outer edge of the ram are displacement transducers which detect deviations from parallelism and send a regulating impulse to hydraulic valve.
